“…websites you visit from our organic search listings will still know that you came from Google, but won’t receive information about each individual query. They can also receive an aggregated list of the top 1,000 search queries that drove traffic to their site for each of the past 30 days through Google Webmaster Tools.

I know a lot of people who aren’t but should be familiar with the Google Webmaster Tools suite. Now’s probably a pretty good time to get that going.
